About this study
Official title: A Study to Evaluate Improvement in the Quality of Life and Outcomes of Patients Diagnosed With Chronic Obstructive Pulmonary Disease (COPD)
- Evaluate subjects in an prospective observational study
- Subjects will be administered scientifically validated questionnaires
- Determine the affect of the Portable Oxygen Concentrator (POC) on improvements in:
- Exercise capability, dyspnea and quality of life as primary endpoints
- Utilize:
- Baseline Dyspnea Index (BDI)
- Transitional Dyspnea Index (TDI)
- Chronic Respiratory Disease Questionnaire (CRQ)
- Six minute walk test (6MWT)
- Epworth Sleepiness Scale (ESS)
- The secondary endpoints will be:
- Rate of exacerbations, sleep quality
- Health care utilization (emergency room encounters, hospital admissions)
Read the detailed description
Evaluate subjects in an prospective observational study in which subjects will be screened and administered scientifically validated questionnaires at study entry and during the observation period at specified intervals to determine the affect of the Portable Oxygen Concentrator on improvements in exercise capability, dyspnea and quality of life as primary endpoints, utilizing the Baseline Dyspnea Index (BDI), Transitional Dyspnea Index (TDI), the Chronic Respiratory Disease Questionnaire (CRQ) and six minute walk test (6MWT). The secondary endpoints will be rate of exacerbations, sleep quality (reported as number of hours sleep improvement; utilize Epworth Sleepiness Scale [ESS]), and health care utilization (emergency room encounters, hospital admissions).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| chronic obstructive pulmonary disease | * More than 12 million adults are diagnosed with COPD * COPD is the 4th leading cause of death in the U.S. * Breathing difficulty is the major reason patients seek medical attention * COPD patients requiring hospitalization were associated with higher costs * Oximetry is an important tool for assessing need for Long-term oxygen therapy * LTOT has been proven to improve survival and quality of life * Patients will be provided a lightweight portable oxygen concentrator to: 1. support increased activity 2. improve quality of life 3. increase functional capacity |
What is being measured
The primary outcome is the main question the study is designed to answer.
Functional Capacity
Change in functional capability, dyspnea - BDI/TDI
- Change in exercise capability - 6MWT
Measured: 6 months
Quality of Life Using Chronic Respiratory Disease Questionnaire
Quality of life - Chronic Respiratory Disease Questionnaire
Measured: Measure Dyspnea at baseline upon study entry and change from baseline every two weeks up to three months; Numerical, 7-point modified Likert Scale; Total score and subscores on categories; higher scores indicate better health-related quality of life

Questions about this trial
What is this clinical trial studying?
An observational study of COPD, run by StratiHealth at 3 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 10 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 20 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Functional Capacity (time frame: 6 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Aug 2018; AzTrials last refreshed its copy on 8 Nov 2026.
